Postfix not listening on 25

Help! (Home for newbies)
1

Hello! I’m setting up a Virtualmin + LAMP stack for the first time and everything works fine except for Postfix. It won’t listen on port 25. I can login via imaps and send mail but they don’t arrive and I can’t receive either.

If I add
smtp inet n - y - - smtpd -o smtpd_sasl_auth_enable=yes
to master.cf it listens on port 25 but there are still no mails incoming and mails out still won’t arrive

This is my main.cf

# See /usr/share/postfix/main.cf.dist for a commented, more complete version

Debian specific: Specifying a file name will cause the first

line of that file to be used as the name. The Debian default

is /etc/mailname.

#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

appending .domain is the MUA’s job.

append_dot_mydomain = no

Uncomment the next line to generate “delayed mail” warnings

#delay_warning_time = 4h

readme_directory = no

See http://www.postfix.org/COMPATIBILITY_README.html – default to 2 on

fresh installs.

compatibility_level = 2

TLS parameters

smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for

information on enabling SSL in the smtp client.

25? Thought that was a no go, try 587.

It’s not working on 587 either and it’s not receiving mails

will you please show the output from postconf -n

It’s finally working!!

I turned on submission service and I just added 'permit_sasl_authenticated ’ to smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination if i remember correctly. I changed the password of two mailboxes and it worked… what’s up with that…?

Well done, loads of issues myself with email and this hosting software.?
